Hello,
Great to be here! Brand new to the forum and the hobby and in the very early planning/research stages of my 29 gallon attempted build. I know I want a little waterfall/creek in my set-up and would like to make the water portion of the tank able to support a few fish(tetras,shrimp etc.) or possibly a newt. My question concerns water changes/filtration. I had a Cichlid tank set-up for about 10 years so I'm no stranger to water changes in an aquarium. What I don't know is how/how often they might be needed in a Paludarium set-up?

Should I plan to drill out the back and install a valve for drainage?
Should I just use a siphon/tank vacuum and do partial water changes?
should I rely on the eventual(biological filter) in a tank pump set-up?

If anyone can point me to any resources on this process, I would greatly appreciate it. Thanks in advance.

Mike
